Performance Analysis
Dense FP16 performance reaches 989 TFLOPS on the GH200 compared with 97.5 TFLOPS dense FP16 on the RTX 4080. This difference means the GH200 completes matrix operations in training workloads at roughly ten times the rate of the RTX 4080 when both operate in dense FP16 mode. Sparse FP16 performance follows the same pattern with 1979 TFLOPS on the GH200 versus 195 TFLOPS on the RTX 4080. Memory bandwidth of 4000 GB/s on the GH200 permits substantially larger batch sizes than the 717 GB/s bandwidth on the RTX 4080 during both training and inference passes.

When to Choose the GH200
The GH200 suits workloads that require 96 GB HBM3 memory and 4000 GB/s bandwidth such as training models that exceed 16 GB capacity. Its 989 TFLOPS dense FP16 rating and 1979 TFLOPS dense FP8 rating further support large scale scientific computing tasks that benefit from the 900W TDP envelope.
When to Choose the RTX 4080
The RTX 4080 fits deployments constrained to 320W TDP and PCIe form factor where 48.7 TFLOPS FP32 performance meets requirements. Its 97.5 TFLOPS dense FP16 rating and 16 GB GDDR6X memory suffice for lighter inference or fine tuning jobs that remain within consumer power limits.
Use Cases
The GH200 supplies 989 TFLOPS dense FP16 and 96 GB HBM3 memory that accommodate large model training.
The GH200 delivers 1979 TFLOPS dense FP8 performance together with 4000 GB/s bandwidth for high throughput inference.
Both GPUs handle fine tuning though the GH200 processes larger batches via 4000 GB/s bandwidth while the RTX 4080 operates at lower 320W TDP.
The RTX 4080 meets Stable Diffusion needs with 48.7 TFLOPS FP32 performance inside a 320W power budget.
The GH200 provides 67 TFLOPS FP32 and 4000 GB/s bandwidth suited to scientific workloads requiring high memory capacity.
Frequently Asked Questions
What is the memory bandwidth difference between the two GPUs?▾
The GH200 reaches 4000 GB/s bandwidth whereas the RTX 4080 reaches 717 GB/s bandwidth. The higher figure on the GH200 supports larger batch sizes in training and inference.
How do the FP16 dense ratings compare?▾
Dense FP16 performance measures 989 TFLOPS on the GH200 and 97.5 TFLOPS on the RTX 4080. The GH200 therefore executes dense FP16 operations at a higher rate.
What TDP values are listed for each GPU?▾
The GH200 lists 900W TDP while the RTX 4080 lists 320W TDP. Power delivery requirements therefore differ substantially between the two cards.
Which GPU offers higher FP32 performance?▾
The GH200 supplies 67 TFLOPS FP32 performance compared with 48.7 TFLOPS FP32 performance on the RTX 4080. The difference favors the GH200 in FP32 workloads.
